As a further improvement l have provided additional means'for 4testing and detiningg anglesand convertible into a square or bevel.

at will, comprising a straight-edge blade C. preferably of metal. graduated in inches and fractions thereof on the edges of the same and pivoted at one end on the endof the straight-edgeA which is uppermost-when used in determining verticals andadapted to swing thereon in either direction. Said plate is slotted longitudinallyv from a. point near its 'center to near said pivoted end, and a blade C" is pivoted on said' straight-edge A by means of the bolt c at a. point beneath the pivot of the blade C and slot-ted 'from near its outer 'end to a point adjacent to the edge of said straightedge A. The outer ends yof said blades are connected by mea-ns o'a fiat-headed 'of 4said plates and is provi ed with a winged nut c', which acts to bind the same rigidly together in any adjusted position, 'as'indicated in Figs. 1 and 7. Said blade C' maf,`- he graduatedon the edges and sides to indicate the point at which the blade C should be secured to indicate a desired angle. v'.lhe blade C lmay also, if preferred, beprovided with a notchv on the upper side of the slot adapted to receive the bolt c when the blade C is ata right angle with the straightfedge A.- The bolt is provided with an angular part fitting in said slots and' acting to hold the boltv from turning.

Vl'hen the blades are not in use, the holt c is removed and the nut c* and the bolt c are changed to the aperture rx in the straight'edge and the blades are placed in the position in l dicated in Fig. 2' and rigidly secured in such position by means of the winged nut c. If

- preferred, the blades may bemade to swing in the opposite direction and fold in a suitable slot in the edge of the straight-edge, as indicated in Fig. 8.

As a further improvement Ihave provided a spring-controlled push-pin D. seated in the edge of the straight-edge and adapted to rest upon the 'edge of the board or other object being operated upon when the device is used as a square or bevel horizontally` butreadily pushed back into the straight-edge when the device is used for plumbing. l have also'provided means for detecting any inaccuracy' of adjustment in the lieveling or plumbing device, which -I term a "telltale, and which consists in providingasegment-shaped recess in the edges of the 'plates L a and a central.

point extending from the plate into said re vThe lower end of theplumbbobis provided with a needle or indicator whichl registers with said point when the needle b' indites the perpendicular, as indicated in Fig.

1, thereby infallibly indicating any imperj fcction or defect in the adjustment of said needle L' to indicate correct-bythescale. 6g

The operation-of u device rrnliotljfngmv' i invention is follmvs'.: When the straightedge 1s placed edgedmvr.. the needle b'swings to the position indimwai in Fig. 3 and indi- Cates level or the angle of inclinutionfrorn horizontal on said scale. ll'hen the straightedge is held vertically. as indicated in Figs.

1 and 2, the needle may also be seen throughthe aperture and' will indicate a vertical po sition on said scale. and any angle of inclination therefrom will be correctly indicated on peculiarly adapted for use in testing levels and for usein bridge-building or other lworlr. where the parts are inclined at deniteangles from the perpendicular` or,`in other words,

said scale.I thereby 'providing an'instrument lnot only for leveling and plumbing. but'also batter. The blades Cand C are particularly useful in setti-ug window and door fra-nes and for other purposes when it is desired to test the angularityI-of,openings with respect to the perpendicular or horizontal. ously many details "f construction may be varied 4from those h-. min shown withoutdeparting from the principle of my invention.
